Population justification: The total population is placed in the band 250-999 mature individuals, equating to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.

Trend justification: A moderate and on-going population decline is suspected to be taking place on the basis of rates of hunting, habitat loss and persecution.
